Background: The current cold weather underwear provides excellent insulation in extreme cold weather, but is too warm in moderate cold conditions. Marines conducting strenuous activity would perspire heavily causing the underwear to lose its insulative qualities. The result was Marines suffering from hypothermia, dehydration and other cold weather injuries. The LWCWUS does not have the deficiencies of its predecessor.
